Due to the remarkable increase of unbalance between power supply and demand as well as load variation

demand response has been widely applied in electricity management in China.Through the use of price and incentive measures

power utilities can guide users to improve their electricity consumption behavior

resulting in effective load management.This paper is intended to make a survey on demand response applications in power system peak shaving

including the feasibility of peak shaving

optimization model and evaluation method.The characteristics of power user's peak shaving are analyzed first.Second

formulation method and the optimization model of peak load management based on electricity price are discussed.Then the paper summarizes the peak shaving researches based on the combination of incentive and price

and the long?term peak shaving considering the participation of demand side resources.The evaluation methods of peak shaving effect by demand response are also introduced.Finally

vistas of this research topic are projected into the future.
